The term 'kind of thermometer' can refer to two different types of thermometers: ORAL and OVEN. An ORAL thermometer is a device used to measure body temperature, usually by being placed in the mouth. An OVEN thermometer is a device used to measure the temperature inside an OVEN, typically placed on the OVEN rack. Both thermometers are used to measure temperature accurately and provide important information for medical and culinary purposes.
